How to use the tire pressure monitoring system in Audi A3?

Audi A3's tire pressure monitoring system operates automatically, and the onboard computer will alert you when there is an issue with the tire pressure. The tire pressure monitoring system is an active safety device that promptly notifies the driver when potential tire hazards are detected, prompting timely actions such as slowing down, stopping to inspect, or seeking necessary roadside assistance, effectively preventing traffic accidents. Here are some details about the tire pressure monitoring system: 1. The tire pressure monitoring system utilizes wireless transmission technology, employing highly sensitive miniature wireless sensors to collect data on tire pressure and temperature, whether the vehicle is in motion or stationary. This data is transmitted to the main unit, where it is displayed digitally in real-time, showing relevant information such as tire pressure and temperature. If any abnormalities are detected, the system alerts the driver through beeps or voice warnings. 2. Tire pressure monitoring systems are categorized into indirect and direct types. The indirect tire pressure monitoring system (WSB) detects when the pressure in any tire decreases, causing the rolling radius of that tire to reduce and its rotation speed to become slightly faster than the other wheels. The system identifies the underinflated tire by comparing these speed differences. The direct tire pressure monitoring system (PSB) uses pressure sensors inside the tires to directly measure the air pressure. The data is then transmitted wirelessly (via Bluetooth or Wi-Fi) to the control module. If any irregularities are found, the system issues an audible warning or displays a warning icon on the dashboard, notifying the driver to check the tire pressure.
When I first drove the Audi A3, I was also curious about how to use the tire pressure monitoring system. It turned out to be quite simple. After parking and turning off the engine, open the central control screen and navigate to the settings menu, then find the vehicle diagnostics option and select the tire pressure monitoring system. Click the initialization button to record the current tire pressure as the baseline. While driving, the system automatically monitors the tire pressure. If there's an abnormality, such as a leak or low pressure, a yellow warning light will illuminate on the dashboard to alert you. I usually manually check the actual tire pressure every two weeks to ensure it matches the system's readings, ideally between 2.2 and 2.5 bar when the tires are cold. Resetting is crucial—repeat the initialization steps after inflating or changing tires to prevent false alarms. Remember to perform this on level ground for more accurate system readings after initialization. This feature once helped me avoid a minor incident and is very practical, also saving fuel.
